Export and its behavior needs to be changed in serveral ways to make it work on Windows and allow better code generation for other plattforms. The Rationale section explains the problem and shows how this DIP solves it.


  • The 'export' protection level should be turned into a 'export' attribute.
  • If a module contains a single symbol annotated with the 'export' attribute all compiler internal symbols of this module should recieve the 'export' attribute too (e.g. module info).
  • If a class is annotated with the 'export' attribute, all of its public and protected functions and members will automatically recieve the 'export' attribute. Also all its hidden compiler specific symbols will recieve the 'export' attribute.
  • It should be possible to access TLS variables which are stored in a DLL / shared library.
